Shop Legrand DX3 MCB 3 Pole 3A Circuit Breaker C Curve | 409249 In Iraq Best Prices
Legrand DX3 thermal magnetic 3-pole circuit-breaker with 3A rating, C curve, 10kA breaking capacity, IP20 protection, and DIN rail mounting for reliable electrical installation protection.
The Legrand DX3 MCB is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a 3-pole configuration, 3A rated current, and C curve release characteristic, this device delivers reliable protection with a 10kA breaking capacity at 400V~. The MCB ensures high fault clearance performance and IP20 finger-safe safety protection, making it ideal for residential and small commercial applications. The device features a built-in depth of 44mm and can be mounted on standard DIN rails with independent removal capability.
This circuit-breaker offers comprehensive protection features including current limiting class 3 for maximum energy limitation according to IEC 60898-1 standard. It is equipped with two DIN rail clamps (top and bottom) allowing convenient installation and removal even when the prong busbar is in place. The device can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, providing flexible installation options. Additionally, it can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality.
The MCB features a label holder for clear circuit identification with On/Off indication printed on the handle with red and green backgrounds for easy status recognition. It operates at a rated voltage of 400V with a rated insulation voltage of 500V and impulse withstand voltage of 4kV. The device maintains performance across a frequency range of 50-60Hz and operates reliably in ambient temperatures from -25°C to 70°C. Being halogen-free and designed with environmental consciousness, this product complies with substance-restriction requirements and RoHS directives.
